Effect of positronium on the -ray spectra and energy deposition in Type Ia supernovae
Anirban Dutta, Andrew Fullard, Wolfgang Kerzendorf +5
Type Ia supernovae (SNe Ia) are powered by the radioactive decay of isotopes such as Ni and Co, making their -ray spectra useful probes of the explosion mechanism…

Analyzing Stellar and Interstellar Contributions to Polarization: Modeling Approaches for Hot Stars
R Ignace, A G Fullard, G V Panopoulou +3
Linear polarimetry of unresolved stars is a powerful method for discerning or constraining the geometry of a source and its environment, since spherical sources produce no net pola…

Introducing STARDIS: An Open and Modular Stellar Spectral Synthesis Code
Joshua V. Shields, Wolfgang Kerzendorf, Isaac G. Smith +7
We introduce a new 1D stellar spectral synthesis Python code called stardis. stardis is a modular, open-source radiative transfer code that is capable of spectral synthesis from ne…
